A retrospective study to assess resource utilization and costs in patients with post-stroke spasticity in the United Kingdom.

OBJECTIVE: Post-stroke spasticity (PSS) is a common complication following stroke. This study describes the differences in healthcare resource utilization between patients who do and do not develop PSS in the UK. METHODS: Adults registered in The Health Improvement Network database with a recorded stroke between 2007 and 2011 were included. PSS was identified through Read codes; machine learning was used to retrospectively identify unrecorded PSS events. Patients with diagnosed or predicted PSS in the 12 months after stroke were matched to those with no PSS on age, sex, number of strokes, socioeconomic status, and comorbidities using the nearest neighbor algorithm. Utilization and costs associated with general practitioner visits, nurse visits, hospitalizations, referrals to specialists, laboratory tests, and medications in the 12 months after stroke were compared. RESULTS: Overall, 2,951 PSS cases were matched to 37,753 controls. During the first year, more PSS cases visited a physiotherapist (19% vs 7%) and occupational therapist (12% vs 5%) compared to controls. A greater proportion of cases were also referred to specialists (76% vs 64%) and hospitalized (33% vs 9%) compared to controls. Medication for spasticity was, on average, 14.68 prescriptions for cases and 5.64 for controls. Total mean costs per patient were £1,270 (standard deviation [SD] = 772) and £635 (SD = 273) for cases and controls, respectively. CONCLUSION: Costs after stroke for patients developing PSS are twice as high compared to patients who do not develop it, with the major driver being the number of hospital admissions. This highlights the need for better recording and closer management of PSS.

Clinical burden of pneumonia, meningitis and septicemia in Norway 2 years after 7-valent pneumococcal conjugate vaccine introduction.

AIMS: This population-based, retrospective study quantified the rates of all-cause and pneumococcal pneumonia, meningitis and septicemia in Norway from 2008 to 2009 and determined the proportions of cases caused by pneumococcal vaccine serotypes. METHODS: Data on patients with all-cause and pneumococcal pneumonia, meningitis and septicemia were obtained from the Norwegian Patient Registry, which collects hospitalization data from all Norwegian public hospitals based on International Classification of Diseases codes. Norwegian Patient Registry case records linked to the Norwegian Surveillance System for Communicable Diseases provided serotype data for invasive pneumococcal disease in patients with microbiological cultures. RESULTS: In 2008 and 2009, hospitalization rates were relatively stable for all-cause pneumonia (5.28 and 5.35, respectively, per 1000), meningitis (10.70 and 9.67, respectively, per 100,000), and septicemia (from 171.81 to 161.46 per 100,000). In contrast, rates decreased for International Classification of Diseases-10 diagnosed pneumococcal pneumonia (from 13.66 to 10.52 per 100,000), although these cases may be under-reported because of inclusion in all-cause pneumonia. Rates also decreased in diagnosed pneumococcal meningitis (from 1.60 to 1.19 per 100,000) and diagnosed pneumococcal septicemia (from 9.08 to 7.94 per 100,000). Diagnosed pneumococcal disease rates were highest in younger children and older adults, peaking at ⩾ 60 years old. Pneumococcal pneumonia, meningitis and septicemia caused by serotypes included in the 7-valent pneumococcal conjugate vaccine decreased substantially during the study period, with corresponding serotype replacement by non-7-valent pneumococcal conjugate vaccine serotypes. CONCLUSIONS: From 2008 to 2009, International Classification of Diseases-10 diagnosed pneumococcal pneumonia, meningitis and septicemia decreased in most age groups but remained greatest among subjects aged 0-1 and ⩾ 60 years.

A retrospective study to assess resource utilization in patients with cervical dystonia in the United Kingdom.

PURPOSE: Cervical dystonia (CD) is a hypertonic condition caused by damage to the central nervous system. Very few studies have assessed the overall economic burden of the disease. The objective of this study was to describe the utilization of health care resources of patients with CD in the UK primary care setting, using a large population-based database. PATIENTS AND METHODS: Adults with a first diagnosis of CD between January 1, 2007 and January 31, 2011, who were registered to a general practitioner (GP) practice contributing to The Health Improvement Network (THIN), were included. Sociodemographic and clinical characteristics were assessed at the time of diagnosis. Health care resource utilization and pharmacological treatment were investigated at the end of the first and second year after diagnosis. RESULTS: Overall, 4,024 newly diagnosed patients with CD were identified, with average age at diagnosis of 45 years old; 65.3% were female. Depression in the year prior to diagnosis was the most common comorbidity. Primary care utilization was high in the first year, with 99.2% of patients visiting their GP (on average 6.2 times), and 43% visiting a nurse (on average 2.5 times). Patients were most commonly referred to an orthopedic surgeon, and 15.9% reported at least one physiotherapy visit. In the second year, utilization was similar. Prescriptions of at least one of the investigated treatments were found in 82.0% and 45.3%, in the first and second year, respectively. CONCLUSION: Findings suggest a high number of new CD cases are being identified in primary care, but not all will be referred to secondary care. Health care resource utilization was compared with that of all patients registered in THIN, which is representative of the UK, and the adjusted usage of primary care resources was found to be similar to that of the THIN population.

Retrospective database study to assess the economic impact of hip fracture in the United Kingdom.

OBJECTIVE: Publications containing recent, real-world data on the economic impact of hip fractures in the UK are lacking. This retrospective electronic medical records database analysis assessed medication and healthcare resource use, direct healthcare costs, and factors predicting increased resource use and costs in adult UK hip fracture patients. METHODS: Data were obtained from the Clinical Practice Research Datalink linked to the Hospital Episode Statistics for adult patients hospitalized for their first hip fracture between January 1, 2006 and March 31, 2011 (index event); healthcare costs were calculated from the National Health Service perspective using 2011-2012 cost data. RESULTS: Data from 8028 patients were analyzed. Resource use and costs were statistically significantly higher in the year following fracture (mean total [standard deviation (SD)] cost £7359 [£14,937]) compared with the year before fracture (mean total [SD] cost £3122 [£9435]; p < 0.001), and were similar to the total amount of the index hospitalization (mean total [SD] cost £8330 [£2627]). Multivariate regression analysis (using an estimated generalized linear model) showed that older age, male gender, higher comorbidity, osteoporosis, discharge to another institution compared with home, and pre-index hospitalization and outpatient visits were associated with increased post-index hospitalization healthcare costs (all p < 0.05). CONCLUSIONS: Although we did not capture all pre- and post-index costs and healthcare utilization, this study provides important insights regarding the characteristics of patients with hip fracture, and information that will be useful in burden-of-illness and economic analyses.
