Incidence and costs of hip fractures in elderly Italian population: first regional-based assessment.

UNLABELLED

We analyzed for the first-time hospitalizations and costs for hip fractures in the elderly Italian population at the regional level from 2007 to 2014. The number of fractures and the overall costs increased, mainly due to people aged > 85 in all the Italian regions, although at different rates.

OBJECTIVE

We aimed at evaluating the burden of hip fractures in elderly Italian population at the regional level.

METHODS

We analyzed national hospitalizations records 2007-2014 to compute standardized hospitalizations rates (SHR) due to hip fractures per 10,000 inhabitants at the regional level and average annual percent change (AAPC), along with related costs.

RESULTS

Hip fractures occurred in people over 65 years increased from 89,601 to 94,525 over 8 years. The overall increase in the number of hospitalizations is attributable only to people aged ≥85. Actually, in the 65-74 and 74-84 age groups, total hospitalizations decreased from 13,396 to 12,268 and from 40,733 to 37,786 respectively, while they increased from 35,472 to 44,471 in people aged ≥85 (women = 28,605 and men = 6,867 in 2007; women = 34,636 and men = 9,835 in 2014). Almost 50% of hip fractures were found to have been experienced by patients aged 85 or older in 2014 (with women ≥ 85 representing 36.6% of total fractures), in accordance with the higher prevalence of osteoporosis in this age group. Fractures increase in people aged ≥ 85 was two-folds higher in males (AAPC: + 5.0%; P > 0.05) than in females (AAPC: + 2.6%; P > 0.05). Increases in the number of hospitalizations and related costs were observed for all the regions, with the only exception of Lazio (AAPC: - 4.6%; P < 0.05) and Friuli Venezia Giulia (hip fractures AAPC: - 1.9%; P < 0.05). The most significant increases in hip fractures and related costs were recorded in Calabria (+ 2.7%), Campania (+ 2.2%), and Lombardia (+ 2.0%). At the national level, SHR per 10,000 inhabitants due to hip fractures decreased in all three examined age groups (65-74, 75-84, and ≥ 85), both in males and females during the 8-year period (P < 0.05). This reduction was confirmed also when looking at the regional dataset, with few exceptions concerning female population (AAPC not statistically significant). When looking at the SHR per 10,000 inhabitants for the entire nation, we recorded a decreasing trend also in females aged 85 years old and over but not in males ≥ 85. Actually, men aged ≥ 85 showed increased HR per 10,000 in 10 regions out of 20. Direct hospitalization and rehabilitation costs increased in all the regions over the 8-year period (although at different rates), except for Friuli Venezia Giulia (where costs decreased from 21 to 19 million Euros) and Lazio (from 107 to 87 million Euros). Lombardia and Piemonte were the regions spending the highest amount of money to treat hip fractures in elderly people (151 and 95 million Euros in the year 2014, respectively).

CONCLUSION

Hip fractures in the elderly population remain a major public health issue in all Italian regions, especially in people aged 85 years old and over, although the problem is starting to become more controlled compared with the past. Women represent the majority of hip fractures, but the highest increasing rate has been observed in men. Pilot projects at regional level targeting elderly people at higher risk of fractures and treatment compliance are needed.
