A care substitution service in the Netherlands: impact on referral, cost, and patient satisfaction

BackgroundIn care substitution services, medical specialists offer brief consultations to provide general practitioners (GPs) with advice on diagnosis, treatment, or hospital referral. When GPs serve as gatekeepers to secondary care, these regional services could reduce pressures on healthcare systems. The aim is to determine the impact of implementing a care substitution service for dermatology, orthopaedics, and cardiology on the hospital referral rate, health care costs, and patient satisfaction.MethodsA before-after study was used to evaluate hospital referral rates and health care costs during a follow-up period of 1 year. The study population comprised patients with eligible International Classification of Primary Care codes for referral to the care substitution service (only dermatology, orthopaedic, cardiology indications), as pre-defined by GPs and medical specialists. We compared referral rates before and after implementation by χ2 tests and evaluated patient preference by qualitative analysis.ResultsIn total, 4,930 patients were included, 2,408 before and 2,522 after implementation. The care substitution service decreased hospital referrals during the follow-up period from 15 to 11%. The referral rate decreased most for dermatology (from 15 to 9%), resulting in a cost reduction of €10.59 per patient, while the other two specialisms experienced smaller reductions in referral rates. Patients reported being satisfied, mainly because of the null cost, improved organisation, improved care, and positive experience of the consultation.ConclusionsThe care substitution service showed promise for specialisms that require fewer hospital facilities, as exemplified by dermatology.

Effects of performance-based capitation payment on the use of public primary health care services in Indonesia

The Indonesian national health insurance agency BPJS Kesehatan, the largest single-payer system in the world, is among the first to combine capitation-based payments with performance-based financing. The Kapitasi Berbasis Komitmen (KBK) scheme for puskesmas (community health centres) was implemented in province capitals between August 2015 and May 2016. Its main goal was to incentivize the substitution of secondary by primary care use. We evaluate its effect on its three incentivized outcomes: the fraction of insured visiting the puskesmas, the fraction of chronically ill with a puskesmas visit and the hospital referral rate for insured with a non-specialistic condition. We use BPJS Kesehatan claims data from 2015 to 2016 from a stratified one percent sample of its members. Comparable control districts were identified using coarsened exact matching. We adopt a Difference-in-Differences (DID) study design and estimate a two-way fixed effects regression model to compare 27 intervention districts to 300 comparable non-capital control districts. We find that KBK payment increased the monthly percentage of enrolees contacting a puskesmas with 0.578 percentage points. This is a sizeable increase of 48 percent compared to the baseline rate of just 1.2% but it still leaves most puskesmas far below the “sufficient” KBK threshold of 15%. For chronically ill patients, a small increase of 1.15 percentage points was estimated, but it leaves the rate even further below the program's “sufficient” threshold of 50%. We find no statistically significant effect on referral rates to hospitals for conditions not requiring specialist care. While we find positive effects of KBK on two out of three outcomes, all estimated effect sizes leave the actual rates far below the program targets. Our findings suggest that the KBK performance-based capitation reform has not been very successful in substituting secondary care use by greater primary care use.

Nationwide community based emergency centers reveal scale of hand trauma

IntroductionThis study describes the characteristics of hand trauma treated in community-based emergency centers (CBECs) in Israel. It was hypothesized that the rate of hand trauma, as well as patient and injury characteristics, would differ from a recent study of patients treated in hospital emergency departments (EDs) in Jerusalem. MethodsData on all hand injury patients treated at any of the CBECs belonging to a large nationwide chain in 2017 were retrieved from the electronic medical records of the treatment centers, including demographic and clinical characteristics. ResultsOver the course of 2017, 53,574 individuals were treated for forearm, wrist and hand injuries (35% of all trauma patients treated during this period). The majority of the patients were male (62%). Contusions and fractures were common (80%) with a minority of lacerations (10%). Crush injuries and amputations were rare. Dog bites accounted for 1.5% of the injuries under the age of 10. Females were treated more with painkillers and opioids, especially over the age of 65, with variability between centers. Although the rate of fractures was similar between teens and the elderly, the elderly were treated with immobilization less frequently, and were referred to EDs for further care. Hospital referral rates differed significantly between centers. DiscussionA higher rate of hand trauma was found in the CBECs in comparison to the hospital ED report (35% vs. 20% of all trauma patients, respectively). Patients treated at the CBECs, in comparison to the ED, were less often male, less often young adults, and differed in terms of type of injury. In the CBECs there were more contusions, as well as fewer lacerations and open wound injuries. In contrast, dog bites in children were found to be much more prevalent than previously reported. Hospital referral indications, the use of immobilization and pain management were found to vary according to age, gender and treatment center. Due to the high rate of hand trauma in CBECs, specific protocols are needed for these patients. The use of opioids should be specifically addressed, considering recent changes in treatment protocols. Thus, the prevalence and characteristics of hand trauma may be biased in studies based on hospital records.

Ongoing effects of eConsultation in nephrology on hospital referral rates: An observational study

Introduction eConsultation in nephrology is an innovative way for general practitioners (GPs) to consult a nephrologist. Studies have shown that questions from GPs can be answered and intended referrals can be avoided by eConsultation. However, follow-up data are lacking. The primary aim of this study was therefore to assess whether patients for whom a referral to the outpatient clinic of a medical specialist was avoided in the short term were not then referred for the same problem within one year after the eConsultation. Methods All eConsultations sent between June 2017 and April 2018 to seven nephrologists in three different hospitals in The Netherlands were included. Exclusion criteria were duplications and missing data on follow-up. Data were obtained from the eConsultation application forms and from GP medical records. Results A total of 173 eConsultations were included. Of the 32 patients for whom a referral was initially prevented, 91% (95% confidence interval 75–98) had not been referred to a specialist for the same problem within one year after the eConsultation. Discussion eConsultation in the field of nephrology can prevent referrals in the long term. It can therefore contribute to a more modern and efficient health-care system in which chronic care is provided by GPs in close proximity to patients, while specialist support is easily available and accessible through eConsultation when necessary.

Assessing the effect of Independent Prescribing for community optometrists and referral rates to Hospital Eye Services in Scotland.

Since 2010, General Ophthalmic Services (GOS) legislation and Independent Prescribing (IP) enable community optometrists to manage primary eye conditions. No studies have assessed the effect of IP. We wished to determine the distribution of IP optometrists and associated hospital referral rates across Scotland. In 2019, FOI requests (General Optical Council and NHS Education Scotland) identified all registered IP optometrists in Scotland and their registered postcodes. Data regarding community eye examinations and referrals to HES since 2010 were gathered via Information Services Division of NHS Scotland. As of March 2019, there were 278 IP optometrists in Scotland (278/1189;23.4%). Two hundred eighteen IP optometrists work in 293 practices across 11 of Scotland's 14 health boards. There was a strong correlation (r = +0.96) between population density and number of IP optometrists. Fifty-six percent of IP optometrists work in the two most deprived quintiles. Since IP's introduction, there has been a marked increase in anterior segment supplementary visits (+290%). Optometry referrals to GPs have reduced by 10.5%, but referrals to HES have increased by 118% (to 96,315). There was no correlation between quantity of IP optometrists and referral rates to HES (r = -0.06, 95% CI -0.64 to 0.56, p = 0.86). This is the first analysis of IP optometrists and associated referral rates in Scotland. Despite good geographical distribution and increased supplementary attendances, optometric referrals to HES have doubled and continue to rise. We propose a ratio of primary, supplementary, non-referral and referral rates to discern the true impact of IP versus non-IP community optometric behaviour.

Choosing the Best and Scrambling for the Rest: Hospital-Nursing Home Relationships and Admissions to Post-Acute Care.

We explored post-Affordable Care Act hospital and skilled nursing facility (SNF) perspectives in discharge and admission practices. Interviews were conducted with 138 administrative personnel in 16 hospitals and 25 SNFs in eight U.S. markets and qualitatively analyzed. Hospitals may use prior referral rates and patients' geographic proximity to SNFs to guide discharges. SNFs with higher hospital referral rates often use licensed nurses to screen patients to admit more preferred patients. While SNFs with lower hospital referral rates use marketing strategies to increase admissions, these patients are often less preferred due to lower reimbursement or complex care needs. An unintended consequence of increased hospital-SNF integration may be greater disparity. SNFs with high hospital referral rates may admit well-reimbursed or less medically complex patients than SNFs with lower referral rates. Without policy remediation, SNFs with lower referral rates may thus care for more medically complex long-term care patients.

Integrated Care in Diabetes: Impact of Email Decision Support on Community Type 2 Diabetes Service in the Midlands in Ireland

Introduction: In Ireland, significant progress in management of patients with diabetes in the community has been made with the introduction of ‘Cycle of Care’ system. However, the Irish system is still heavily dependent on secondary care for management of patients with type 2 diabetes and integrated care between the community and secondary care remains haphazard. Since 1998 the Midlands Structured Diabetes Programme has been providing structured care in the community for patients with type 2 diabetes. This involves 3-4 patient visits per year with care being delivered by GP and practice nurse, supported by Community Nurse Specialists. Since 2011 the CNSs have been able to access support from secondary care as part of evolution of the programme to tie in with proposed National Model of Care. Objective: 1) improve glycaemic control of complex patients with type 2 diabetes 2) lower hospital referral rates and hospital admission rates 3) empower GPs and community nurses to manage more complex patients with type 2 diabetes Methods: The decision support consisted of specific case emails sent by the community diabetes nurses in Westmeath and Longford to the specialist endocrinologist in Regional Hospital Mullingar, in relation to strategy for improving glycaemic control of individual patients attending different GP practices enrolled in the Structured Care Programme. Data was collected for cases between 2011 and 2016. Results: Demographics: Mean Age: 65 (+/- 12.6) Gender = 34 Male 26 Female Glucose control Mean baseline HbA1c from the year 2011 – 2015 is 61.3mmol/mol [± 15.4, (n=44)]. 1 year after the advice, HbA1c improve to 59.1 [±13.3 (n=25)], at 2 years is 62.5mmol/mol [± 13.2 (n=21)], at 3 years is 62.2mmol/mol [± 15.9 (n=17)] and at 4 years is 63.0mmol/mol[± 12.3 (n=20)]. Proportion of patients with improved glycaemic control in 1 year after the advice is 48% (n=12/25), at year 2 is 52% (n=11/21) and in year 3 is 47% (n=8/17) Complications: 30% (n=18) had macrovascular complications. 15.0 % (n=9) of patients had chronic kidney disease. 10.0 % (n=6) had previous stroke or TIA. 16.7% (n=10) had ischaemic heart disease. Type of referral Glucose management: 90.0 % (n=54) Driving advice: 1.6% (n=1) Advice on cardiovascular risk: 5.0% (n=3) Conclusion: Email Decision Support of patients with complex Type 2 Diabetes Mellitus in the community setting leads to improved glucose control and is sustainable and assists in service development and efficiency. This can potentially be applied to the new ‘Cycle of Care’ diabetes care system in the Irish Health Service.

Low hospital referral rates of school scoliosis screening positives in an urban district of mainland China.

Significant prevalence rates of adolescent scoliosis in China were suggested in previous studies. However, school screenings for adolescent scoliosis have been suspended due to low rates of positive detection under the past screening system in China. The present study was undertaken to screen for adolescent scoliosis in middle school students under a modern assessment system in a district of Shanghai. We performed a population-based, cross-sectional study of a middle school scoliosis screening program in the Jingan district. In 2015, schoolchildren were initially screened by visual inspection of clinical signs and the forward-bending test. Suspected cases were referred for radiography in hospital for scoliosis diagnosis. A total of 5327 middle school students (grades 6–8) were screened with 520 (9.76%) positives (the positive rates of girls and boys at 15.28% and 4.59%, respectively) and no statistically significant difference among grades. Only 301 positives (57.9%) followed the referral for hospital radiography. There were 102 cases (33.9%) that were diagnosed with scoliosis by radiography criteria (Cobb angle ≥10°) including mild scoliosis (Cobb 10–25) for 94 cases and moderate scoliosis (Cobb 25–40) for 8 cases, and false-positives (Cobb 0) for 39 cases. The putative prevalence rate was estimated as 1.9% from the referred students. Under an accurate and modern assessment system, school screenings can detect scoliosis at a significant rate, but awareness of scoliosis risks is needed for residents in China to take up referrals for hospital diagnosis after school screenings.

Epidemic Gasoline Exposures Following Hurricane Sandy

Major adverse climatic events (MACEs) in heavily-populated areas can inflict severe damage to infrastructure, disrupting essential municipal and commercial services. Compromised health care delivery systems and limited utilities such as electricity, heating, potable water, sanitation, and housing, place populations in disaster areas at risk of toxic exposures. Hurricane Sandy made landfall on October 29, 2012 and caused severe infrastructure damage in heavily-populated areas. The prolonged electrical outage and damage to oil refineries caused a gasoline shortage and rationing unseen in the USA since the 1970s. This study explored gasoline exposures and clinical outcomes in the aftermath of Hurricane Sandy. Prospectively collected, regional poison control center (PCC) data regarding gasoline exposure cases from October 29, 2012 (hurricane landfall) through November 28, 2012 were reviewed and compared to the previous four years. The trends of gasoline exposures, exposure type, severity of clinical outcome, and hospital referral rates were assessed. Two-hundred and eighty-three gasoline exposures were identified, representing an 18 to 283-fold increase over the previous four years. The leading exposure route was siphoning (53.4%). Men comprised 83.0% of exposures; 91.9% were older than 20 years of age. Of 273 home-based calls, 88.7% were managed on site. Asymptomatic exposures occurred in 61.5% of the cases. However, minor and moderate toxic effects occurred in 12.4% and 3.5% of cases, respectively. Gastrointestinal (24.4%) and pulmonary (8.4%) symptoms predominated. No major outcomes or deaths were reported. Hurricane Sandy significantly increased gasoline exposures. While the majority of exposures were managed at home with minimum clinical toxicity, some patients experienced more severe symptoms. Disaster plans should incorporate public health messaging and regional PCCs for public health promotion and toxicological surveillance.

Antianginal Therapy Before Percutaneous Coronary Intervention

The regional variability of percutaneous coronary intervention (PCI) rates may be explained by variations in the medical treatment of stable coronary artery disease. We sought to determine whether greater regional use of antianginal medications in PCI patients is associated with lower regional rates of PCI. Using CathPCI Registry and Dartmouth Atlas data, we examined patients undergoing elective PCI for stable coronary artery disease from January 1, 2009, through March 31, 2011, and calculated rates of providing ≥ 2 antianginal medicines before PCI. We regressed the hospital referral region rates of PCI per 1000 Medicare enrollees in 2007 on the regions' rates of providing ≥ 2 antianginal medications before PCI. Among 300772 PCI procedures, 32.8%, 48.3%, 16.1%, and 2.8% of patients were on 0, 1, 2, or ≥ 3 antianginal medications, respectively. The median rate of providing ≥ 2 antianginal medications before PCI was 18.9%. Although substantial variability existed across hospital referral regions in providing ≥ 2 antianginal medications and in rates of PCI from the Dartmouth Atlas, there was no association between the rates of PCI in each hospital referral region and the rates of ≥ 2 antianginal medications before PCI (Spearman ρ, 0.0277; P=0.64). We found no association between the intensity of antianginal therapy and the use of PCI across hospital referral regions, despite the variability of both. Opportunities likely exist in many regions to increase the use of antianginal therapy before proceeding to elective PCI, and more research is needed to explain observed variations in care.

Abstract 335: Cardiac Rehabilitation Referral After Acute Myocardial Infarction: Variation in Referral Rates and Association with Core Components of Risk Factor Management

Background: Although currently an endorsed performance measure of quality, cardiac rehabilitation (CR) referral rates remain quite low. Established guidelines describe recommended core components of CR programs for risk factor management: nutritional counseling; physical activity counseling; exercise training; smoking cessation; and weight, hypertension, lipid, diabetes, and psychosocial management. We sought to determine the variability in hospital referral rates for CR and assess whether patients are more likely to be referred who have risk factors that are intervention targets of the core components of CR. Methods: We assessed referral to outpatient CR among 3632 MI patients from 22 US hospitals in the TRIUMPH study who were discharged home with risk factor data available. Variation in CR referral rates across hospitals was quantified by the median rate ratio (MRR). The prediction of CR referral by 8 individual risk factors that are intervention targets of CR was assessed using hierarchical modified Poisson regression, adjusting for study site and 16 demographic and clinical patient characteristics. Results: Upon hospital discharge, only 39.1% (n=1420) of patients were referred to CR. Referral rates varied greatly across sites, ranging from 2.6% to 88.2%. After adjusting for potentially confounding patient factors, the MRR was 2.47 (95% CI 1.67, 3.23), indicating an average 2.5 times greater likelihood of 2 hypothetically identical patients being referred to CR upon discharge from 1 random hospital as compared with another. Only 1 of 8 risk factors modifiable by CR core components was associated with increased referral (see figure), with overweight patients (BMI > 25 or waist circumference > 40 in. for men, > 35 in. for women) being more likely to be referred than non-overweight patients (RR 1.09; 95% CI 1.03, 1.15; p<0.01). Conclusion: Among patients discharged home after MI hospitalization, there are marked differences in outpatient CR referral rates by study site, but relatively little association with patient risk factors that the core components of CR programs are specifically designed to modify. This suggests that site-specific factors strongly influence CR referral and site-level interventions to improve referral are likely to most effectively improve compliance with this performance measure.

Prevalence and medical risks of body packing in the Amsterdam area

AimBody packing is a way to deliver packets of drugs across international borders by ingestion. The aim of the study was to provide an estimate of the medical risks of body packing, describe predictors for hospital referral in detained body packers and provide an estimate for the prevalence of body packing in the Amsterdam area. MethodsFrom May 2007 to December 2008, we studied medical records of body packers immediately detained after arrival at Amsterdam Schiphol airport, hospital records of both detained body packers and self-referrers at two emergency departments of hospitals in Amsterdam and records kept by forensic physicians in charge of post-mortem examinations of all unnatural deaths in the area (years 2005–2009). ResultsIn airport detainees, the hospital referral rate was 4.2% (30 out of 707 detained body packers), the surgery rate was 1.3%. Significant predictors of hospital referral were delayed production of drug packets after arrest, cigarette smoking and country of departure. The surgery rate in self-referrers was comparable to the rate observed in those referred from the detention centre to hospital (30% vs. 31%). In addition, from 2005 to 2009, 20 proven cases of lethal body packing were identified. Based on our data, it is estimated that minimally 38% of all incoming body packers were missed by airport controls. ConclusionThe risk for lethal complications due to body packing is low on a population basis and comparable to other studies. This also applies for the hospital referral and surgery rates found in this study. Cigarette smoking has not yet been described in the literature as a potential predictor for hospital referral in detained body packers and therefore deserves attention in future research. A substantial fraction of body packers manages to remain undiscovered.

The Breast Imaging Reporting and Data System (BI-RADS) in the Dutch breast cancer screening programme: its role as an assessment and stratification tool

ObjectivesTo assess the suitability of the Breast Imaging Reporting and Data System (BI-RADS) as a quality assessment tool in the Dutch breast cancer screening programme.MethodsThe data of 93,793 screened women in the Amsterdam screening region (November 2005–July 2006) were reviewed. BI-RADS categories, work-up, age, final diagnosis and final TNM classification were available from the screening registry. Interval cancers were obtained through linkage with the cancer registry. BI-RADS was introduced as a pilot in the Amsterdam region before the nationwide introduction of digital mammography (2009–2010).ResultsA total of 1,559 women were referred to hospital (referral rate 1.7 %). Breast cancer was diagnosed in 485 women (detection rate 0.52 %); 253 interval cancers were reported, yielding a programme sensitivity of 66 % and specificity of 99 %. BI-RADS 0 had a lower positive predictive value (PPV, 14.1 %) than BI-RADS 4 (39.1 %) and BI-RADS 5 (92.9 %; P < 0.0001). The number of invasive procedures and tumour size also differed significantly between BI-RADS categories (P < 0.0001).ConclusionThe significant differences in PPV, invasive procedures and tumour size match with stratification into BI-RADS categories. It revealed inter-observer variability between screening radiologists and can thus be used as a quality assessment tool in screening and as a stratification tool in diagnostic work-up.Key Points• The BI-RADS atlas is widely used in breast cancer screening programmes. • There were significant differences in results amongst different BI-RADS categories. • Those differences represented the radiologists’ degree of suspicion for malignancy, thus enabling stratification of referrals. • BI-RADS can be used as a quality assessment tool in screening. • Training should create more uniformity in applying the BI-RADS lexicon.

The Relationship between Hospital Admission Rates and Rehospitalizations

Efforts to reduce hospital readmissions have focused primarily on improving transitional care. Yet variation in readmission rates may more closely reflect variation in the underlying hospitalization rates than differences in the quality of care during and after discharge. We used national Medicare data to calculate, for each local hospital referral region (HRR), the 30-day, 60-day, and 90-day readmission rates among patients discharged with congestive heart failure or pneumonia. We also calculated population-based all-cause admission rates among Medicare enrollees in each HRR. We examined the variation in HRR readmission rates that was explained by overall hospitalization rates versus differences in patients' coexisting conditions, quality of discharge planning, physician supply, and bed supply. HRR readmission rates ranged from 11 to 32% for congestive heart failure and from 8 to 27% for pneumonia. In univariate analyses, all-cause admission rates accounted for the highest proportion of regional variation in readmission rates for congestive heart failure (28%, 34%, and 37% at 30, 60, and 90 days, respectively); the next highest proportions were explained by case mix (11%, 15%, and 18%) and the number of cardiologists per capita (12%, 14%, and 15%). Results for pneumonia were similar, except that the number of pulmonologists per capita accounted for a lower proportion of the variation (6%, 8%, and 7%, respectively). In multivariate analyses, admission rates accounted for 16 to 24% of the variation for congestive heart failure and 11 to 20% for pneumonia; no other factor accounted for more than 6%. We found a substantial association between regional rates of rehospitalization and overall admission rates. Programs directed at shared savings from lower utilization of hospital services might be more successful in reducing readmissions than programs initiated to date. (Funded by the Commonwealth Fund.).

Comparison of the long‐term effects of simple total abdominal hysterectomy with transcervical endometrial resection on urinary incontinence

To test the hypothesis that the hospital referral rate for urinary incontinence (UI) symptoms, within 10 years of a simple total abdominal hysterectomy (TAH) for dysfunctional uterine bleeding (DUB), would differ to that after a transcervical resection of the endometrium (TCRE). Retrospective case note review. Teaching hospital in north east Scotland. All women who had a TAH (316) or a TCRE (229) for DUB, during the period from 1 January 1990 to 31 December 1994, who had never been referred for symptoms of UI prior to their operation. Independent t tests, Mann-Whitney U tests and Chi-squared tests were used to compare the two study groups in terms of demographic details and outcome measures. Newcombe's method for the comparison of two unpaired proportions was used to calculate 95% CIs for the differences in outcome measures between the two operations. Logistic regression was conducted to investigate associations with hospital referral for UI. Hospital referral for UI at 10 years follow up. There were significantly more hospital referrals for UI in the TAH group compared with the TCRE group (46 [15%] versus 16 [7%]; OR 2.27, 95% CI 1.25-4.12). More women were referred for urological investigations after a TAH than after a TCRE (39 [12%] versus 13 [6%], 95% CI for the difference in proportions 2-11%). A higher, but statistically nonsignificant, proportion of women had objectively demonstrated UI after a TAH than after a TCRE (25 [8%] versus 10 [4%], 95% CI for the difference in proportions -1 to 8%). There were a greater number of hospital referrals for treatment of UI in the TAH group (36, 11%) than in the TCRE group (12, 5%), 95% CI for the difference in proportions (1-11%). After adjusting for age, weight, smoking status and mode of delivery, the increased rate of hospital referral for UI after TAH remained, with an odds ratio of 2.31, 95% CI 1.24-4.30. TAH is associated with a significantly increased incidence of hospital referral for UI, urological investigations and treatment for UI at 10 years of follow up compared with TCRE.

Oral contraceptives and benign breast disease: an update of findings in a large cohort study

Background This report is an update of findings, first reported in 1981, on the relationship between oral contraceptives (OCs) and benign breast disease with special reference to OCs containing <50 mcg estrogen. Study Design The Oxford-Family Planning Association study includes 17,032 women using different methods of contraception recruited at 17 family planning clinics between 1968 and 1974. These women were subsequently followed up until mid-1994. Among other items, information about contraceptive method changes and morbidity as measured by hospital referrals was collected during follow-up. Results The findings in the present analysis were broadly similar to those reported in 1981, but based on much larger numbers of cases [fibroadenoma (FA), 185 cases; chronic cystic disease (CCD), 1361 cases; breast lump with no specific diagnosis (BL), 650 cases]. Hospital referral rates for FA and CCD (but not BL) declined with increasing duration of OC use, with the effect being strongest among recent users. The apparent protective effect was present for women using OCs containing >50 mcg, 50 mcg and <50 mcg estrogen but not for progestogen-only OCs. Conclusion Low-dose combined OCs containing <50 mcg estrogen appear to reduce the risk of hospitalization for FA and CCD as well as older preparations containing higher doses of estrogen.

Nurse telephone triage in out-of-hours GP practice: determinants of independent advice and return consultation

BackgroundNowadays, nurses play a central role in telephone triage in Dutch out-of-hours primary care. The percentage of calls that is handled through nurse telephone advice alone (NTAA) appears to vary substantially between GP cooperatives. This study aims to explore which determinants are associated with NTAA and with subsequent return consultations to the GP.MethodsFor the ten most frequently presented problems, a two-week follow-up cohort study took place in one cooperative run by 25 GPs and 8 nurses, serving a population of 62,291 people. Random effects logistic regression analysis was used to study the determinants of NTAA and return consultation rates. The effect of NTAA on hospital referral rates was also studied as a proxy for severity of illness.ResultsThe mean NTAA rate was 27.5% – ranging from 15.5% to 39.4% for the eight nurses. It was higher during the night (RR 1.63, CI 1.48–1.76) and lower with increasing age (RR 0.96, CI 0.93–0.99, per ten years) or when the patient presented >2 problems (RR 0.65; CI 0.51–0.83). Using cough as reference category, NTAA was highest for earache (RR 1.49; CI 1.18–1.78) and lowest for chest pain (RR 0.18; CI 0.06–0.47). After correction for differences in case mix, significant variation in NTAA between nurses remained (p < 0.001). Return consultations after NTAA were higher after nightly calls (RR 1.23; CI 1.04–1.40). During first return consultations, the hospital referral rate after NTAA was 1.5% versus 3.8% for non-NTAA (difference -2.2%; CI -4.0 to -0.5).ConclusionImportant inter-nurse variability may indicate differences in perception on tasks and/or differences in skill to handle telephone calls alone. Future research should focus more on modifiable determinants of NTAA rates.

Outcomes of chlorine exposure: a 5-year poison center experience in 598 patients

The outcome after chlorine exposures has been poorly described. We conducted a 5-year retrospective poison control center review of chlorine exposure cases. The inclusion criteria were self (or surrogate) reported concentrated 'chlorine' liquid (> or =10% concentration of sodium hypochorite) or tablet (> or =90% concentration) exposure. Two reviewers blinded to the main purpose of the study reviewed charts and a third reviewed 10% of the charts, and a kappa score was calculated. Parameters reviewed included the type of exposure (tablets, liquid or both), symptoms (cough, chest pain, etc.), time to symptom onset, treatment received, hospital referral rate and outcomes. A total of 598 patient records were reviewed, with a mean age of 29.63 years (range 11-82); 41.5% (248) were exposures to tablets and 53.5% (320) were exposed to liquid chlorine, with the remainder exposed to both. Complaints included shortness of breath, eye irritation, nasal complaints, cough, and skin complaints. Sixty-nine patients were evaluated at a healthcare facility (11 referred by a poison control center and 58 were self-referrals). Five patients were admitted and four out of the five had a history of reactive airway disease. The mean time to peak symptoms was 94.4 min, 63.2% reached peak symptoms within 30 min, and 82% within 120 min, with 74% of all patients asymptomatic within 150 min. All five admitted patients were discharged within 48 h, and all others remained clinically well at a 24 h telephone follow-up. Exposure to chlorine tablets and liquid rarely requires hospital referral with almost all symptoms resolving within 24 h.
